Granted: 2012-09-10
Abstract: Procedimiento para aplicar partículas de diamante en una capa de polvo metálico ligante.#La invención se refiere a un procedimiento para aplicar partículas de diamante sobre una capa de polvo metálico ligante, para fabricar herramientas con superficies abrasivas. En cada secuencia operacional las partículas son aspiradas de un contenedor y mantenidas por aspiración contra una superficie aplicadora de unos medios aplicadores. Operaciones posteriores son: realizar un barrido de la superficie aplicadora; trasladar los medios aplicadores desde el contenedor hasta quedar encima de la capa de polvo metálico; bajar los medios aplicadores hasta introducir la superficie aplicadora en el polvo metálico; interrumpir la aspiración de partículas, depositándolas en la capa; empujar las partículas individualizadamente al interior de la capa; y someter el contenedor, antes de la aspiración de partículas, a una vibración para desapelmazar el contenido, repitiéndose tantas veces dicha secuencia como capas de partículas a aplicar en la superficie abrasiva.

Title: Vibrating dryer
Inventor: JAMEEL SAMI HADDAD
Filed: 2009-11-03
Granted: 2011-02-27
Abstract: The subject matter of this invention relates to a vibrating dryer used for drying wet products in powder and granular form, the drying chamber of said machine is provided with plurality of shelf sets. The shelves in each set are overlapped horizontally and are slightly elevated over each other vertically. The shelves of each set are connected to each other with a single rotating beam fixed to the centers of said shelves, the ends of said beam are provided with grips that allows the user to rotate said beam by a desired angle . Such mechanism offers a mean for rotating each set as a whole. The shelves of each set are also connected to a rotating handle and a rotating mechanism that allows the user to pivot the shelves of each set simultaneously around their centers by a desired angle . Such structure offers two degrees of freedom for each shelf which is beneficial for varying the angle depending on the dried material and for cleaning and unclogging said shelves by rotating them to a vertical position. The shelves sets are also overlapped horizontally, but are significantly elevated over each other. Such elevation will cause the dried materials to fall from a considerable distance whenever said materials pass from one set to another. The overlapped configuration of said shelves will elongate the descending period of wet material, which will cause an elongated exposure to hot air and will help the dried materials to mix.
